Abstract The study of energy losses in any electric installation is

closely related to energy efficiency. Its calculation depends on the

number and the quality of the available electrical measurements.

Typically, every wind park has electrical measurements in all its

wind turbines and its HV point of connection. However, it is

difficult to calculate in an easy way these losses due to problems

like redundancy, inaccuracy, lack of data, etc.

A state estimation (SE) method will be proposed in this article, inorder to calculate the power losses. By means of available

measurements (power, voltage, current...) and parameters of the

network (cables, transformers...), the losses taking place in each

element can be obtained. SE also allows detecting errors in

measurement and calculating the wind park state when certain

measurement equipments are unavailable. Wind speed

measurements are used to get pseudo-measurement if necessary

and to filter errors.

Finally, an economic study will be done taking into account the

different ways of selling wind energy in the Spanish network.

Consequently, the economic importance of losses will be

evaluated too.

The location of this project is The Sotavento Wind Park, Serra daLoba, Spain. The results shown throughout this article have been

applied there with the aim of analysing its energy efficiency.

I. INTRODUCTION

Measurements devices rarely cover all the electricalmagnitudes in an installation, e.g. a wind park; that is whymany electrical variables cannot be obtained directly. In thisway, a study of energy efficiency starts from measurements soas to obtain the magnitudes related to efficiency. This could be

done thanks to a power flow; before the remaining values couldbe calculated, measurements must be supposed to be correct.Nevertheless, measurements devices have specific errorsrelated to their precision and accuracy; besides, they could beworking improperly due to breakdowns or communicationsfailures. Where measurement errors are taken into account toobtain the network state [1][2][3], a SE method can be appliedto overcome these problems. From network state, losses in any

network element can be calculated, so that energy efficiencyfor the installation can be obtained.

In the following paragraphs, it is presented a method forenergy efficiency calculation in the Sotavento ExperimentalWind Park [4]. In the first part there is a description of the wind

park, then, the SE method is introduced, and lastly, electricaland economical results are shown.

II. SOTAVENTO EXPERIMENTAL WIND PARK

The project, called Sotavento Galicia S. A., was born in1997 promoted by the Consellera de Industria e Comercio(Department for Industry and Trade), one of the departments ofthe Xunta de Galicia (local government) [4]. Its objective wasto obtain not only economic, but also scientific and technical

benefits. Three public institutions are taking part in this project,with a total amount of 51% of its capital.

The Sotavento Experimental Wind Park has installed 24wind turbines with a total power of 17,56 MW and anestimated annual energy production of 38,500 MWh (seeFigure 4).

There are two 20 kV underground lines where the MV sideof wind turbine transformers are connected. Each line haslinked 12 wind turbines. The central control building is fedfrom one line.

This work was produced as part of a research project and was supportedby Sotavento Galicia, S.A.

The 20kV lines are connected to a 132kV/20kV substationwhere an auxiliary services MV/LV transformer, two capacitor

banks and the main 132kV/20kV transformer are installed.Parameters of transformers, wind turbines, cables and capacitor

banks are shown in Appendix.

Reactive compensation is done by means of capacitor banksinstalled in the LV side of wind turbines and in the substation[5].

Measurement devices for voltage, current, active power andreactive power are installed in all the wind turbines and in thesubstation. There is neither any measurement in the 20 kV sideof the wind park, nor information about the Power FactorCorrector (PFC) installed in the substation.

Since wind speed and direction are taken into consideration,data extracted from the measurement tower (installed in the

park) are used (see Figure 1).

III. ESTIMATION OF ENERGY LOSSES

Electrical measurements in a network have shown someincertitude about precision and accuracy of measurementdevices, communication problems, breakdowns, and so on.Hence, it could not be directly used to know the network state.As a consequence, an SE is necessary to get over these

problems; it can be defined as the method to calculate the statein a network whose parameters and topology are known fromredundant measurements.

The minimum number of variables that allow determiningthe network state are known as state variables. Any electricalvariable can be calculated from them. These state variables arethe modulus and angle of nodal voltages, and from them anestimation of any electrical variable can be obtained, includingthose that have been measured. In that case, the value usedmust be the estimated one.

In SE a minimum of measurement, distributed in anappropriate way, must be known to have a topologicalobservable network. There are 58 nodes in the SotaventoExperimental Wind Park, so, it is necessary a set of 115

measurements. At least, 57 of them must be active powermeasurements and another 57 must be reactive ones.

In the wind park there are 29 active and reactive power andvoltage measurements; according to the previous paragraph thewind park network does not seem to be observable. However,from node 30 to 55 there is no power injection, so virtualmeasurements can be considered for these nodes. In the controlcenter building (node 56) active and reactive energy aremeasured every 15 minutes. Thanks to these measurementsmean power values can be obtained and used as pseudo-measurements.

There is not any reactive power measurement in thesubstation capacitor banks (nodes 57 and 58); the curves shownin Figure 2 are used with the aim of estimating their state.These curves are fitted in the gaps detected in the active andreactive power, which are injected by the wind park to the132kV network (node 29). The values obtained are used as

pseudo measurements of reactive power, also, a value zero for

active power is used as virtual measurement.

As a resume in TABLE I the available measurements forSE are shown, the total number of real, virtual and pseudomesurements garatentees the redundancy. Furthermore, thenetwork is topological observable because it is a radial networkwith more than 57 measurements of active and reactive power,and with more than one voltage measurements [6].

A variance or weight is calculated for each measurement, itrepresents the confidence in the measurement device,supposing that their errors follow a Gauss distribution. In thecase of Sotavento Wind Park, all the measurement devices arethe same; for that reason, an equal variance is assigned to all ofthem. In case of a non-existent measurement, they are

substituted by pseudo-measurements, which are obtained fromthe rest of measurements. The variance for these pseudo-measurements much be higher than than those for normal ones(e.g. ten times higher), because the associated error is highertoo.

The SE method used in this paper is weighted least squaremethod with restrictions. These restrictions are the virtualmeasurements, those that have associated null active andreactive powers.

IV. RESULTS

The SE has been applied over one year measurement data.Therefore, all the instantaneous electrical magnitudes related toenergy efficiency have been calculated. It is by means of theseresults that an estimation of the yearly generation and thedistribution losses can be done. As an example, in Figure 3 theestimated and measured values for active power, reactive

power and voltage in wind turbine 11 are shown. Wind turbine

communication was lost from 3970 hours, so, pseudo-measurements were used for SE.

Wind turbine generation is distributed between networklosses, wind park consumption and power injected fromsubstation. Energy is produced in wind turbines, one part is

injected to the 132kV network and the rest is consumed or lost(see Figure 5). Reactive energy comes from capacitors banks,MV lines and 132kV network, its distribution over the wind

park elements is shown in Figure 6.

V.

ECONOMIC ANALISYSIn Spain, the remuneration of wind energy consists in the

implementation of a regime by which each kWh generated ispaid to the producer at a special price, higher than the marketone [5][7][8][9].

The legal and economic status of wind power installationsis currently regulated by Royal Decree (RD) 436/2004. Wind

power producers have the right to choose between two options:

A) First option consists in selling the electricity to thedistribution company. The owner of the installations will beentitled to receive as remuneration:

A regulated tariff per kWh applied to all their output.

This tariff consists of a percentage of the AverageElectricity Tariff (AET) published every year.

Plus a reactive power service supplement and asupplement for continuity against voltage dips.

B) The second option is to sell the electricity freely in themarket. In this case the remuneration is:

The hourly price per kWh in the electricity pool or theprice freely agreed with the purchaser.

Plus a premium per kWh that consists of a percentageof AET.

Plus an incentive per kWh for participating in themarket, it also consists in an AET percentage.

Plus a reactive power service and continuity of thesupply against voltage dips supplement.

Plus a capacity payment.

C) Plants remaining in the previous RD2818/1998 had theoption to sell the electricity at the market price with a subsidy.The subsidy had annual revisions according to the evolution ofART and annual average market price. The option might befreely exercised up to January 1, 2007.

By means of years data and applicating the SE, the resultsshown in TABLE II of the efficiency for the three options

depicted above can be calculated. The losses in the wind parknetwork and the consumption in the Central Control (CC)building are presented.

The energy losses represent 2.96% of the energy generatedby the wind parks. For options A and B, this percentage has thesame value when it is calculated from energy prices. In theoption C (Market Sales), the energy price depends on themarket and the percentage of losses is higher. The conduct ofthe energy consumed by the control center building is similar.

VI. CONCLUSIONS

The main conclusions of this study are:

Taking one year of measurement data a SE method hasbeen used to estimate the energy efficiency of a windpark. Errors in measurements and lack of data havebeen overcome by using pseudo-measurements.

Losses represent a 2.84% of the energy generated bywind turbines; consumption of CC building representsa 0.32%, and what is left: 96.8% is the energy injectedto the 132 kV network.

Capacitor banks generate a 38.1% of reactive energyconsumed in the wind park, a 32.5% is generated bythe MV lines, and the rest: 29.3% comes from 132kV

network. The reactive power generated by MV lines isvery close to those consumed in substation and windturbine transformers. The average power factor is0.9983.

From an economic point of view, the cost of energylosses is between 2.95% and 2.99% of the price of theenergy produced. In accordance with the CC building,

the percentage of its energy consumption varies from0.33% to 0.34 %.

Welcome to EPQU07 in Barcelona

It is our honour and pleasure to invite you to the 9th

International Conference on

Electrical Power Quality and Utilisation, taking place this time in Barcelona, Spain.

As a consequence of the technical quality and especial social atmosphere that hasalways characterized this series of conferences, the number of submitted papers shows a

steady trend to increase. On this occasion, over 350 papers have been reviewed by the

Scientific Committee, of which only 227 have been accepted for oral presentation.

Many good papers had to be rejected because of the upper limit imposed by the number

of parallel sessions. Apart from regular papers, the technical programme is completed

with several tutorials, plenary sessions and a panel session that closes the conference.

The present 9th EPQU Conference is the continuation and development of previous

conferences on the same or similar subject-matter, which have been organized in Poland

by Electrical Power Engineering Institute of Technical University in Lodz and Instituteof Electrical Drive and Industrial Equipment Control of AGH-University of Science and

Technology in Krakow (since 1997) in collaboration with Azov Technical University of

Mariupol (Ukraine) and Ukrainian National Academy of Sciences (Institute of

Electrodynamics).

The first one entitled Electrical Power Quality in National Electrical Power System took

place in Lodz in 1987. The next one entitled Electrical Energy Quality was organized in

Spala (Poland) in 1991, and was followed by the third one named Efficiency and

Quality of Electrical Power Supply for Industrial Plants, which was held in Mariupol

(Ukraine) in 1994.

Since 1997 all conferences have been organized in Krakow with the same name:

ELECTRICAL POWER QUALITY AND UTILISATION - 1997, 1999, 2001, 2003,

2005.

In 2005 the members of EPQU Conference scientific committee decided to change the

place of the next 9th EPQU Conference to Spain and organize it in collaboration

with CITCEA-UPC (www.citcea.upc.edu). We are sure that it was very good decision!

Thanks to our several sponsors, particularly ENDESA, the registration fee for the

EPQU07 is similar to past editions. We believe the social programme, traditionally

composed of a reception, excursions and a gala dinner, is quite attractive and will satisfy

the most exigent attendant.

The Local Organising Committee has made its best to assure that your stay in Barcelona

is fruitful and joyful. The origins of Barcelona are previous to the Roman presence. The

first stable human settlement may be located in the 6th century BC. Later, in the 3rd

century BC, a not enough contrasted legend attributes to the Cartaginese leader

Hannibal, the son of Amilcar Barca, the foundation of the city. The Romans came toBarcelona because of the wars that the two great Mediterranean powers, Roma and

Cartago, fought by the end of the 3rd century BC. After the definitive Cartaginese

defeat, the Romans incorporated the city to their domains.

The Barcelona of the 21st century is a city shaped by the '92 Olympics, a city

transformed for and by the need to do justice to that great international event. The

Barcelona we see around us now, the Barcelona we enjoy today, is a new Barcelona,

Mediterranean in keeping with its traditions, with its face to the sea and its arms open to

other cultures and peoples, giving and receiving, happy to make and to share its riches.

The Barcelona of the 21st century is an European capital of astonishing cultural energy

and a passion for progress, a city whose day-to-day life brings together every

imaginable facet of the most diverse activities: these are the potential that has fashioned

the city's present and give it the impetus to move forward into the future.

We are looking forward to welcoming you in Barcelona!

Yours sincerely,

Antonio Gmez Expsito

Conference Chairman

WINE CELLARS AND MONTSERRATMagic day in the Catalonian Holy mountain and the Codorniu cellars

10thOctober - all day

An outing to the Codorniu cellars, in the Peneds area, about 30 Kilometresfrom Barcelona. The Peneds is the wine-growing region which created the

cava, a sparkling wine vintage of worldwide renown. During the trip you willvisit the cellars and see the winemaking process. Then we shall go to

Montserrat, the holy mountain of Catalonia, a majestic mountain about 60kilometres from Barcelona. It name comes from its special silhouette, cut by

erosion into a saw shape. The Royal Basilica houses the picture of thelegendary Virgen Morena, patron saint of Catalonia. Catalan lunch not far

from Montserrat.

BARCELONA GAUD TOURModernist designs and Colours

11thOctober - morning

The Modernist movement is reflected in the architecture of the Eixample district.A central sector of the Eixample is the Quadrat dOr (Golden Square) because ofits concentration of Modernist Buildings. A trip through the Catalan Modernism -Art Deco, Modern Style - an artistic current which manifested in Europe around

the turn of the century whose main features are the variety of forms and therichness of its decorative elements. A large proportion of the masterpieces of

modernist architects such as Gaud, Domnech i Montaner and Puig i Cadafalchare concentrated in the Eixample quarter. A visit to the Templo de la SagradaFamlia (Holy Temple), probably the most famous of Gaudis works, is still being

built according to his initial project. The catalogue of constructions by Gaud doesnot end here, we can visit the masterpiece of his work: the Parque Gell, nowUNESCO heritage, where nature and art coexist in a same place. This fantasy

garden is also one of the best spots from which the city can be seen.
